  • Patent number: 10086164
    Abstract: A medical joint and a check valve module thereof are used in a connection tube having a communicating opening. The check valve module includes a first membrane and a second membrane. The first membrane is assembled to the communicating opening to seal the same. The first membrane includes a first slit. The first membrane and the second membrane are disposed overlappingly. The second membrane includes a second slit. Accordingly, it facilitates inserting a detector into the connection tube to detect gas pressure, MDI, gas, temperature, or inserting a suction tube to remove sputum, and prevents the gas inside the connection tube from leaking out from an intersection of a first slit and a second slit, thereby achieving handiness and a gas-leak-proof effect of the medical joint and the check valve module.

  • Publication number: 20150038910
    Abstract: The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for bypassing a septum to open the blood control catheter valve. The actuator includes flexible retention arms positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve.

    Abstract: An exemplary infusion system for accessing an implanted device is disclosed comprising an insertion assembly, a hub comprising a sealable path configured to receive at least a portion of the insertion assembly, a flexible catheter attached to the hub and configured to receive at least a portion of the insertion assembly, and an extension tube attached to the hub. The hub may comprise a manifold element configured to provide fluid communication between the flexible catheter and the extension tube. The hub may also comprise a septum configured to seal the sealable path upon removal of the insertion assembly from the flexible catheter. The extension tube may also be configured to receive at least a portion of the insertion assembly. Exemplary methods of providing a fluid communication path to an implanted device are also disclosed.

  • Patent number: 8636686
    Abstract: The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.

  • Patent number: 8622967
    Abstract: An intravenous catheter device is provided which includes a catheter adapter having a fluid chamber, a needle adapter being slidably positioned within the fluid chamber, the needle adapter supporting a base of an introducer needle and a terminal end of a section of intravenous tubing such that a fluid pathway of the introducer needle is in fluid communication with a fluid pathway of the section of intravenous tubing. Following catheterization, the needle adapter is slid to a preferred proximal position whereby a sharpened tip of the introducer needle is shielded within a catheter of the intravenous catheter device, or a portion of the fluid chamber of the catheter adapter. When in the preferred proximal position, fluid communication between the catheter and a section of intravenous tubing is facilitated via the hollow body of the introducer needle.

  • Patent number: 8622971
    Abstract: An access apparatus for use during a surgical procedure to provide access to the interior of the body includes an access member defining a longitudinal axis and having a proximal end for being disposed at an exterior side of the body and a distal end for extending into the interior of the body. The access member has a bore therethrough dimensioned to permit passage of an object. A seal is disposed within the bore of the access member. The seal includes a fabric material and an elastomeric material, and defines an internal passageway dimensioned to form a substantial sealing relation with an object inserted therethrough.

  • Patent number: 8591476
    Abstract: An intravascular valve component broadly includes a valve case and a flexible pressure-actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall and an annular flange surrounding the central valve wall. The annular flange includes a radially-extending flange wall and a projection extending axially from the flange wall, with the projection engaging one of the case portions to restrict radial movement of the flow control valve relative to the valve case.

  • Patent number: 8562569
    Abstract: A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

  • Patent number: 8500715
    Abstract: Fluid communication to an end of a catheter is afforded through a connection hub selectively attachable thereto. The connection hub includes a catheter receiving element and a fluid coupling element that are relatively rotatable coaxially between a catheter receiving condition and a catheter capture condition of the connection hub. The catheter capture condition, a compressible sealing sleeve disposed interior of the connection hub between a pair of clamping jaws projecting from the catheter receiving element is urged into sealing engagement with the exterior of the catheter, catheter is gripped mechanically through the sealing sleeve by the clamping jaws. The exteriors of each of the catheter receiving element and the fluid coupling element are formed into planar actuation handles that facilitate relative rotation of the catheter receiving element and the fluid coupling element into coplanar alignment in the catheter capture condition of the connection hub.
